LUBRlCATOR.

SPECIFICATION forming part of Letters Patent N 0. 738,835, datedSeptember 15, 1903.

Application filed November 27, 1901. Renewed May 4:, 1903. Serial No.155,680. (No model.)

To all whom, it may concern:

Be it known that we, WILLIAM C. NEEL- INGS and EUGENE J. GAY, bothcitizens of the United States of America, and residents of Algona,Kossuth county, Iowa, have jointly invented certain new and usefulImprovements in Lubricators, of which the following is a specification.

The object of this invention is to provide means for lubricating an axleof a carriage, wagon, buggy, or other wheeled truck with hard-oil orother lubricant without removing a wheel from said axle or loosening theattachment thereto.

Our invention consists in the construction, arrangement, and combinationof elements hereinafter set forth, pointed out in our claim, andillustrated by the accompanying drawings, in which- Figure 1 is a sideelevation of an axle, show- I ing an axle-skein mounted thereon and ourimproved lubricator attached in position for practical use. Fig. 2 is alongitudinal section of the device shown in Fig. 1.

In the construction and mounting of the device, as shown, the numeraldesignates an ordinary axle-bar, preferably made of iron or steel andsurmounted by an axletree 11, of wood, attached thereto by a clip 12 ina common manner. An axle 13 is formed on or welded to one end of theaxle-bar 10, and an axle-skein 14 is shown mounted on the axle andsecured by an axle-nut 15 in a common manner. The axle 13 is formed witha cylindrical portion 13 at its inner end and a groove 16 in andlongitudinally of the periphery of its tapering body portion, one end ofthe groove being adjacent the cylindrical portion and the other end ofsaid groove being near the outer end of the axle. A hole 17 is formed inthe cylindrical portion of the axle 13 at an angle to the trend thereofand extending inward from the periphery toward the center of theaxle-bar. A passage 18 is formed in the inner end of the axle leadingfrom the top of the axle-bar to and communicating with the hole 17 atits inner end. A pipe 19 is mounted obliquely in the outer end portionof the axletree 11 and enters at its outer end the inner end of thepassage 18. A cup 20 is mounted on the upper rounded portion of theIclip12 and is formed with lips 21 21, only one of which is shown, dependingon each side of and embracing said clip. It is the function of the lipsto brace the cup on the clip and form a seat on the rounded uppersurface thereof, and a bolt 22 is mounted through said lips and clip andsecurely seats the cup on the clip removably and replaceably. The upperend of the pipe 19 extends through the bottom of the cup 20 and securessaid cup to the clip as well as communicates with theinterior thereof.The cup 20 is of cylindrical form and is interiorly screw-threaded. Aplug 23 is screwed into the cup 20 and is formed with a stem 24, angularin cross-section and centrally located on its upper end. It will beobserved that the plug is relatively thin and is concaved in its lowersurface. Thus is provision made for the storage of a considerable supplyof hardoil or other lubricant in the cup beneath the plug when the plugis removed.

The insertion of the plug forces a portion of the lubricant into thepipe 19, passage 18, and hole 17, thus providing space for the firmmounting of the plug, as shown. Further screwing of the plug 23 into thecup by means of a Wrench applied to the stem 24 will force a portion ofthe lubricant out of the hole 17 upon the periphery of the cylindricalportion 13 of the axle 13, where it is received by the axle-skein 14 andspread evenly over the axle. Any surplus of lubricant forced into thebearing will enter the groove 16 and spread therefrom as required. Byreason of the n1aterially less width of the stem 2% than the diame- 'terof the plug 23 a wrench may follow said stem into the cup and screw theplug entirely to the bottom thereof. The concave in the bottom of theplug provides a chamber to hold lubricant after the plug has reached thelimit of its inward movement, thus insuring the presence of lubricanteven after the operator ascertains that he can no longer force it fromthe cup.

We claim as our invention- In a lubricator for vehicles, the combinationof an axle formed with a groove 16 longitudinally of the upper porti nof its periphery and a hole 17 formed in th 'nner end portion of theaxle 13 and at an le to the trend thereof extending inward and downwardfrom the periphery toward the center, the outer end of said hole beingspaced apart from the adjacent end of the groove 16, a passage 18 beingformed in the inner end of the axle and leading from the top of theaxle-bar downward and outward to a point of communication with the hole17, an axletree 11 mounted on the axle-bar, a clip mounted removably andreplaceably on and connecting the axletree and axle-bar, a pipe 19mounted obliquely through the axletree in alinement and communicatingwith the upper end of the passage 18, the upper end of said pipeextending through the clip, an oil-cup mounted on 15 said clip andformed with a hole in its bottom connected with the upper end of thepipe 19, lips on said cup embracing said clip, a bolt mounted throughsaid lips and clip and a plug formed with a concaved bottom, screwedinto 20
